KNITTING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 245,136, dated August2, 1881.

Application filed May 2, 1881.

I0 all whom it may concern:

Beit known that I, SWITS OONDE, ofOswego,

in the county of Oswego and State of New York, have invented new anduseful Improvements inKnitting-Machines,'of which the following, takenin connection with the accompanying drawings, is a full, clear, andexact description.

The purpose of this inventionis to knit on a circular-knittin g machinehorizontally-striped fabric without carrying on said fabricloosethreads, or varying or impairing the texture thereof, all of which isaccomplished by instrumentalities hereinafter fully described, andspecifically set forth in the claim.

In the annexed drawings, Figure l is a side elevation of the meansemployed for producing horizontally striped knitted fabric as aforesaid.Fig. 2 is a plan view of same below the line at as. Fig. 3 is a frontview thereof, and Figs. 4 and 5 are enlarged detail views illustratingthe efiect of the invention.

Similar letters of reference indicate corresponding parts.

A represents the so-called needle-cylinder of a rotary-knitting machine,and N the bearded needles secured vertically on said cylinder.

Lrepresents the loop-wheel or burr, arran ged at the outside of thecylinder A, for the purpose of carrying into the needles the yarn orthread to be knitted.

a denotes the usual stationary thread-guide which feeds the yarn orthread to the loopwheel. To the side of said stationary threadguide Ipivot two or more vibratory threadguides, 12 I), which are made toalternately and intermittently rise and fallat intervals of one or morecomplete revolutions of the needlecylinder by the medium of thefollowing instrumentalities.

To an arm, a, projecting from the standard 8, is pivoted a rockarm, a,which, at points equidistant from the pivot, bears against the underside of the thread -guides b b. To one end of the rock-arm is connecteda pendent pitman, d, the lower end of which passes through a guide, is,which sustains it laterally. Under the pitmanis a ratchet-wheel,e,mounted horizontally on a post, a, in such relative (No model.)

position as to bring the foot of the pitman to bear on the upper siderofthe ratchet-whee], near the edge thereof, as best seen in Fig. 3 of thedrawings.

9 gdenote cams in the form of blocks permanently secured or cast on thetop of the ratchet-wheel in such relative position as to pass under thefoot of the pitman when the ratchet wheel is rotated, said blocks being.bey'eled on the end to allow the pitman to slide upon them in theirapproach. The ratchet wheel, being sustained in a horizontal position,causes the pitman to rise and fall as the cams 9 pass under it. Aspring,I, connected at one end to the rock-arm and at the opposite end to theguide It or other stationary object, serves to draw the pitman down uponthe face of the ratchet-wheel after the cam g has passed from under thepitman. This intermittent reciprocating motion of the pitman dimparts acorresponding intermittent oscillating motion to the rock-arm c, which,in turn, lifts the threadguides 12 b alternately and intermittently.

The ratehetwheel receives its motionby a lever, h, which is pivoted onthe post a, and

.has one end arranged in the path of a cam, f, on

the needle cylinder A, and the opposite end provided with a pawl, m,which is held in con tact with the teeth of the ratchet-wheel by aspring, 1". The rotation of the needle-cylinder causes the cam ftoswingthe lever h, so that the pawl m will turn the ratchet wheel 6 thedistance of one of its teeth. A spring, a, con nected to the post a orother stationary point and exerting on the lever h a force in an opposite direction from the movement ofthe needle-cylinder, restores thesaid lever to its original position, the latter movement being determined bya suitable stop, 10, arresting the said reverse movement ofthe lever.

To prevent the pawl m from drawing back with it the ratchet-wheel e, ajam nut, 0, is applied to a screw-threaded stud on the end of the post aand afriction-washer, o, interposed between said nut and the hub of theratchetwheel. By tightening the jam nut sufficient friction can beobtained on the ratchet-wheel to prevent its retrograde movement asaforesaid.

The described mechanisms can be regulated to knit horizontal stripes ofany desired width, either by attaehii'ig to the needle cylinder A agreater or less number of cams,f, so as to move theratchetwheel more orless frequently during each revolution of the needle-cylinder, or bysimply applying, to the ratchet-wheel a greater or less number of cams,g, and bringing said cams at shorter or longer intervals under thepitman d, which actuatesthethrcadguides in the manner aforesaid. i

The operation of my invention is as follows: The vibratory thread guidesare to he Sup plied with difi'erentlycolored threads or yarns, which arepassed simultaneously into the beards of the needles by the usualloop-wheel or burr L. The alternate and intermittent rising and fallingof the thread guides raises one thread above the other alternately, eachthread being retained in its elevated position during a definite numberof revolutions of the l needle-cylinder by a proper adjustment of theactuating mechanism of the thread-guides in the manner before described.The elevation of the thread-guide increases the tension on itsrespective thread, and thus holds the same toward the front of theneedle, while the other thread, carried slack beneath the tautthread, isallowed to be drawn back ofthe latter, and so retained by the previouslyformed loop, which is drawn over the said threads and elf the needles inthe usual manner, as illustrated in Figs. 4 and 5 of the drawings. Thedili'ercntly-colored threads being thus made to al ternately appear atthe surface of the fabric during a definite number of revolutions of theneedle cylinder produces the horizontallystriped fabric, and, since allthe threads or yarns are invariably passed into the needles, no loosethreads are carried on the fabric, and the fabric is rendered of auniform texture.

What I claim as my invention is- In combination with the vibratorythreadguides b b, rock-arm c, and pitman d, the guide 7:, spring 1,ratchet-wheel 6, provided with the cam 9, post a, jam nut 0, frictionplate 0, spring a, and lover lb, provided with the pawl m, the stop 1;,and the cylinder A,provided with the cam f, all combined and operatingsubstantially in the manner dcscri bed and shown.

In testimony whereof I have hereunto signed my name and afiised my seal,in the presence of two attesting witnesses, at Oswego, in the county ofOstvego, in the State of New York, this 19th day of April, ISSL SWITSUONDE. [L.
